Ergonomically designed bicycle saddle

ABSTRACT

Embodiments of the invention provide a customizable bicycle saddle for a bicycle. The bicycle saddle has been designed to allow it to be adjusted to match the ischial tuberosities of each rider&#39;s pelvis in order to minimize the pressure placed on other portions of the rider&#39;s body while seated on the bicycle. The bicycle saddle comprises a first seating portion that has been configured to allow a rider to sit on the bicycle, a second seating portion that has been configured to allow the rider to sit on the bicycle. The bicycle saddle also includes a first adjustment means configured to allow the first seating portion to be moved closer to the second seating portion, and a second adjustment means configured to allow the saddle to be moved closer to a forward portion on the bicycle.

BACKGROUND

The following description includes information that may be useful in understanding embodiments of the invention. It is not an admission that any of the information provided is prior art or relevant to the claimed invention, or that any publication specifically or implicitly referenced is prior art.

Poorly designed bicycle saddles or seats have been associated with numerous physical injuries for both men and women. Cycling problems for men related to poor bicycle saddle design include: prostatitis, saddle sores, erectile disfunction, incontinence, urethritis, and testicular pain. Cycling problems for women related to poor bicycle saddle design include incontinence, local trauma (bruising, rubbing, and inflammation), vaginitis, urinary tract infections, prolapse, and saddle sores.

Such problems are sufficiently common and severe to warrant coverage in various media. According to one report, a professional UK bicyclist required complicated genital surgery due to injuries caused by long-term use of a poorly designed bicycle saddle. (https://www.dailymail.co.uk/health/article-6850943/Team-GB-cyclist-reveals-needed-VULVA-surgery-years-saddle.html). When sensitive skin is exposed to friction it can cause the tissue to become rough and bleed, and may lead to infection, according to one surgeon.

Some women have even undergone surgery to remove parts of the vagina to make cycling more comfortable. A London surgeon disclosed in a 2016 article that she had seen rising numbers of women requesting labiaplasty (also known as “saddle surgery”), a painful procedure that involves cutting off part of the inner labia to stop it from rubbing and being pinched against bicycle saddles. The American Society of Plastic Surgeons also revealed that demand for labiaplasty had spiked 40 percent, with members performing 12,000 of the operations.

Yale University scientists writing in the Journal of Sexual Medicine found that cycling more than 100 miles per week—not a long distance for many cyclists—may damage the genitals. Researchers found this level of exercise led to an increase in pain and numbness and generalized “sexual dysfunction” for some cyclists. Excessive cycling may also lead to recurrent thrush or urinary tract infections. Another study published in the same journal found that 60 percent of competitive women cyclists suffer genital pain.

Some efforts can be found in the prior art to improve the design of bicycle saddles by generally making conventional saddle designs more comfortable, as opposed to reconsidering how a human should properly sit on a bicycle for an extended time period.

Therefore, for the reasons discussed above, a need exists for a more robust solution to the problem of providing the public with a bicycle saddle or seat that has been developed to provide comfort and safety for long duration riding.

SUMMARY OF THE INVENTION

Embodiments of the invention comprise a bicycle saddle for a bicycle that includes a first adjustable seating portion, the first adjustable seating portion shaped to accommodate a first of a user's two ischial tuberosities, such that a first portion of a mass of the user's upper body rests on the user's first ischial tuberosity on the first adjustable seating portion.

DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTION

Embodiments of the invention provide an improved bicycle saddle or seat that has been designed to accommodate human anatomy, particularly the anatomy of the human pelvis, to provide support and comfort for cyclists, especially cyclists on long-duration tours.

The prior art in bicycle saddle design focuses primarily on receiving pressure in the human midline but not directly in helping the bicycle saddle cope with a proper distribution of human weight-bearing. Consequently, it's easy to see how soft tissue when seated on a bicycle saddle becomes squashed up and outwards from the midline. By comparison, a visit to a zoo shows monkey backsides with calluses where their weight goes when sitting, and humans and monkeys are both primates, sharing a common ancestor and similar pelvic structure.

In addition, male and female pelvis dimensions are very different, with women having a significantly greater width between their weight-bearing ischial tuberosities. Some studies indicate that the mean ischial tuberosity width for women is 135.3 mm and for men is just 114 mm. From an anatomical point of view, it's easy to see how soft tissue is squashed up and outwards from the midline when a rider is seated on a conventional bicycle saddle that has been designed as a one-size-fits all saddle.

Some of the features that embodiments of the invention aim to provide include:

-   -   1. Adjustability of the bicycle saddle to ensure that the         primary support for a rider's weight is under the ischial         tuberosities and that the front of the bicycle saddle is         comfortable, and     -   2. That the bicycle saddle is more concave on top than convex to         help the rider's posterior stay properly supported on the         ischial tuberosities or “sit bones”.

The inventor has observed that bicycle saddles (or seats) have shrunk in recent years but do not make allowance for the fact that human weight bearing, when sitting, should mainly reside on the ‘ischial tuberosities’ (‘IT’s) of the pelvis. In other primates these often are highlighted by calloused areas of skin on their backsides where there is buildup of solid skin to cope with the focal weight-bearing on hard surfaces. Nevertheless, in cycling, bicycle saddles have narrowed radically, and the weight-bearing is often taken away from the pelvic bones, ultimately resulting in soft tissue damage.

FIG. 01 illustrates a bicycle saddle 104, according to an embodiment of the invention. As shown in FIG. 01, a human pelvis 100 includes two ischial tuberosities 103 a, 103 b. The two ischial tuberosities 103 a, 103 b represent the anatomical structures upon which a human body should preferably rest (e.g., carry the load bearing weight of the body's upper torso) when a person is seated or when riding a bicycle. As mentioned above, the width between the ischial tuberosities 103 a, 103 b differs from person to person and especially between men and women.

The bicycle saddle 104 includes two regions 105 a, 105 b situated approximately below and aligned with the ischial tuberosities 103 a, 103 b when the rider is seated on the bicycle saddle 104. The properly situated rider should then be able to ride comfortably for an extended period of time because the rider will have his/her weight centered on the regions 105 a, 105 b and not on some other region of the seat 104, according to an embodiment of the invention.

The seat 104 may be shaped to further facilitate the rider centering his/her weight in the regions 105 a, 105 b. For example, sloping the seat 104 in such a manner that the rider's body came to rest with the ischial tuberosities 103 a, 103 b centered on the regions 105 a, 105 b would help accomplish this objective, according to an embodiment of the invention. The regions 105 a, 105 b may also represent holes in the saddle 104, according to some embodiments of the invention. When present, such holes may provide further guidance to users in terms of proper seating location. However, in many cases it may be equally satisfactory to adjust or construct the seat 104 itself such that the user naturally sits in the regions 105 a, 105 b, which serve as a primary weight-bearing region for the bicycle saddle 104, according to an embodiment of the invention. Thus, the bicycle saddle 104 operates on an anatomically sound principle.

There are several ways for arranging the structure associated with various embodiments of the bicycle saddle 104 to achieve the key features provided by embodiments of the invention:

-   -   1. Adjustability of the saddle 104 width to suit the rider's         pelvic bones.     -   2. Concavity of the saddle 104 to keep the rider's bottom seated         properly.

Some embodiments of the saddle 104 may include removable “plugs” that file holes in the regions 105 a, 105 b in the bicycle saddle 104 to further ensure adjustment of the rider's weight to correct for the lowest portion of the user's anatomy.

Because the distance between the ischial tuberosities 103 a, 103 b varies from male to female (and person to person), the bicycle saddle 104 should preferably be adjustable to allow for these individual differences—or be built to account for these anatomical differences. In other words, the bicycle saddle 104 should preferably include a means to vary the distance between the regions 105 a, 105 b to match differing ischial tuberosities 103 a, 103 b, according to an embodiment of the invention. In addition, a gap along the middle of the bicycle saddle 104 could alleviate damage to organs such as the prostate for male riders and the vulva for female riders. Thus, an overall goal for embodiments of the bicycle saddle 104 is to maximize the rider's comfort by taking weight properly and protecting the “soft tissue” components near the pelvis 100.

As noted, a user of bicycle saddles associated with embodiments of the invention should have the width of his/her ischial tuberosities measured or determined in order to adjust the bicycle seats correctly. The academic literature indicates that it can be difficult to measure precisely where the weight bearing points 103 a, 103 b are on the pelvis 101.

The distance between the ischial tuberosities 103 a, 103 b may be measured using the following procedure. A foam block may be placed on a short stool positioned next to a wall. Users may place their backs flat against the wall and lower themselves onto the foam resting on the stool. Once an initial impression has been made on the foam, the user may pull up on the foam and press down again to ensure that a deep measurable impression has been made in the foam. Small spherical objects, such as ball bearings, may rolled on the foam indentations until they come to rest at the deepest points of the impressions. The width of the ischial tuberosities 103 a, 103 b may be determined by measuring the distance between the ball bearings with a ruler, yardstick or tape measurer. Similarly, a user may sit on a soft surface (in a riding position, for example) and put both hands under the user's bum to feel where the two pressure points of ischial tuberosity 103 a, 103 b reside, then stand up and mark the points. Even this simple approach provides reasonably accurate results.

Alternatively, if the user has an X-ray, CT scan, or the like of the pelvic region, the ischial tuberosities 103 a, 103 b may be precisely measured. Of course, the measurement will need to account for any scaling of the image versus the actual size of the user's pelvis.

As another alternative, special measuring embodiments of the adjustable bicycle seats described herein may be employed as devices for measuring a user's ischial tuberosities. For example, the regions 105 a, 105 b shown in the bicycle saddle 104 in FIG. 01 could be turned into holes and by repeated adjustments of the distance between the two regions 105 a, 105 b, the user's ischial tuberosities may be determined. In place of a fixed piece bicycle saddle such as the bicycle saddle 104, an adjustable bicycle saddle such as the bicycle saddle 404 a shown in FIG. 04, or the bicycle saddle 606 shown in FIG. 06, or the bicycle saddle 1300 shown in FIG. 13 may be more suited to taking such measures. The holes in these saddles would correspond to a location in those saddles deigned to be the optimal location for a user's ischial tuberosities 103 a, 103 b. FIG. 20 illustrates a series of markings 2014 that may aid in the adjustment of the saddle 2000 itself to match the ischial tuberosities 103 a, 103 b.

As shown in many of the figures, the two adjustable seating portions are not intended to touch each other (e.g., the adjustable seating portions 1910 a, 1910 b shown in FIG. 19 are maintained some distance apart in operation). The open space between the two adjustable seating portions is intended to provide enhanced safety for the user and intended to solve some of the health and safety problems previously mentioned. Commercial embodiments of the invention may include adjustable seating portions of differing sizes. A user should select a seating size whose combined distances from seat center to seat edge are less than the user's ischial tuberosity width, e.g., a user with an ischial tuberosity width of 14 cm could choose seats having an overall width of 7.62 cm (the distance from each seat's center to seat edge is 3.81 cm, leaving a separation between the two seats of 6.38 cm (14 cm−(3.82 cm×2)=6.38 cm).

The typical user's ischial tuberosity separation is not likely to change with any frequency. Consequently, once a user has measured this distance, then the user will likely not need to have the measurement made again, assuming that an accurate measurement has been made.

FIG. 2 illustrates three exemplary bicycle saddles 204 a, 204 b, and 204 c for women riders, according to an embodiment of the invention. Each bicycle saddle includes left regions 205 aa, 205 ba, and 205 ca and right regions 205 ab, 205 bb, and 205 cb that correspond to the regions 105 b, 105 a shown in FIG. 1 and should align with each respective user's ischial tuberosities when the rider is properly seated in the bicycle saddle 204 a, 204 b, and 204 c.

The bicycle saddle 204 c is narrower than the saddle 204 b, which itself is narrower than the saddle 204 a. The bicycle saddles 204 a-204 c have been customized for their respective riders after a proper measurement of their ischial tuberosities, according to an embodiment of the invention. In other embodiments of the invention, the bicycle saddles 204 a-204 c may actually be the same saddle but adjusted to be wider or narrower to suit a particular rider. In such embodiments, the bicycle saddles 204 a-204 c have still been customized for the unique ischial tuberosities of each rider but could theoretically adjusted to accommodate another rider. Thus, such a design approach would likely be amenable to mass production.

As discussed with the regions 105 a, 105 b in FIG. 1, the regions 205 aa, 205 ab, 205 ba, 205 bb, 205 ca, and 205 cb might include holes to help the rider locate a proper seated position, and these holes might also be accompanied by plugs that could be used to fill in the holes, according to an embodiment of the invention.

The area 206 b, 206 c outline areas where the bicycle saddles 204 b, 204 c should take caution to be extra comfortable for the rider in order to minimize the chance of injury. The bicycle saddles displayed thus far—saddles 104, 204 a, 204 b, and 204 c have a conventional triangular shape. As discussed in conjunction with further embodiments of the invention, removal of the tip point of the seat triangle, such as the areas 206 b and 206 c, may reduce the rider's chances of injury further.

FIG. 3 illustrates three exemplary bicycle saddles 304 a, 304 b, and 304 c for male riders, according to an embodiment of the invention. Each bicycle saddle includes left regions 305 aa, 305 ba, and 305 ca and right regions 305 ab, 305 bb, and 305 cb that correspond to the regions 105 b, 105 a shown in FIG. 1 and should align with each respective user's ischial tuberosities when the rider is properly seated in the bicycle saddle 304 a, 304 b, and 304 c.

The bicycle saddle 304 c is narrower than the saddle 304 b, which itself is narrower than the saddle 304 a. The bicycle saddles 304 a-304 c have been customized for respective riders after a proper measurement of their ischial tuberosities, according to an embodiment of the invention. In other embodiments of the invention, the bicycle saddles 304 a-304 c may actually be the same saddle but adjusted to be wider or narrower to suit a particular rider. In such embodiments, the bicycle saddles 304 a-304 c have still been customized for the unique ischial tuberosities of each rider but could theoretically adjusted to accommodate another rider. Thus, such a design would be amenable to mass production.

As discussed with the regions 105 a, 105 b in FIG. 1, the regions 305 aa, 305 ab, 305 ba, 305 bb, 305 ca, and 305 cb might include holes to help the rider locate a proper seated position, and these holes might also be accompanied by plugs that could be used to fill in the holes, according to an embodiment of the invention.

The area 306 b, 306 c outline areas where the bicycle saddles 304 b, 304 c should take caution to be extra comfortable for the rider in order to minimize the chance of injury. The reader may notice that the areas 306 b, 306 c are longer and larger than the areas 206 b, 206 c shown in FIG. 02. The reason for the larger area for the male areas 306 b, 306 c relates to the male anatomy, particularly the rider's testicles. As mentioned above, the bicycle saddles displayed thus far have a conventional triangular shape. As discussed in conjunction with further embodiments of the invention, removal of the tip point of the seat triangle, such as the areas 306 b and 306 c, may reduce the rider's chances of injury further.

FIG. 4 illustrates a bicycle saddle 404 a, 404 b, 404 c shown with differing amounts of separation between two adjustable seating portions 405 a, 406 a, according to an embodiment of the invention. The saddles 404 a-404 c could represent different saddles or the saddles 404 a-404 c could represent the same saddle, provided the saddle includes a mechanism for controlling the separation between the adjustable seating portions 405 a, 406 a.

Thus, saddles 404 a-404 c correspond to the “fixed” saddles 204 a-204 b shown in FIG. 02 and the “fixed” saddles 304 a-304 c shown in FIG. 03. Instead of using the distance between the rider's ischial tuberosities to build a customized saddle made for that user, the saddles 404 a-404 c allow a user who knows the distance between their ischial tuberosities to adjust the saddle 404 a-404 c to fit that distance, according to an embodiment of the invention.

The adjustable seating portions 405 a, 406 a, each respectively include a support bar 405 a, 405 b, which would likely be embedded in the saddle 404 a-404 c to avoid direct contact with the user. The support bar may attach to a standard parallel rod support fixed to a standard bicycle frame bracket that holds the saddle 404 a-404 c.

FIG. 04 also shows the saddles 404 a-404 c from behind on a horizontal plane that corresponds to each saddle 404 a-404 c. Each saddle 404 a-404 c includes a representative attachment 407 a, 407 b, 407 c that reflects how far apart the saddle's adjustable seating portion 405 a is from its counterpart adjustable seating portion 405 c, which allows customization to the user's ischial tuberosities, according to an embodiment of the invention.

FIG. 05 illustrates a bicycle saddle 504 in profile, according to embodiment of the invention. The saddle 504 includes a support bar 505 a that ultimately attaches to the support pole 510 coming from the bicycle frame (not shown). Various types of attachment devices may be used in combinations with various embodiments of the invention shown in all the figures herein to attach the bicycle saddles to the bicycle frame.

The bicycle saddle 504, in addition to being adjustable for the user's comfort with respect to the user's IT may also be adjustable to allow for a comfortable distance from the bicycle handlebars, according to an embodiment of the invention. In other words, the bicycle saddle 504 is configurable to be moved closer to the bicycle handlebar, according to an embodiment of the invention.

FIG. 06 illustrates an adjustable bicycle saddle 606 that aims to provide a proper distance between the user's ischial tuberosities and minimize the stress on the user's posterior area, according to an embodiment of the invention. The bicycle saddle 606 includes two padded adjustable seating portions 604 a, 604 b that may be spaced apart at an optimal distance between the user's ischial tuberosities, according to an embodiment of the invention. The padding material used in the two padded adjustable seating portions 604 a, 604 b may comprise various Shore Durometer measurements, e.g., 15-30 on the Shore 00 scale. The adjustable seating portions 604 a, 604 b may comprise a roughly circular circumferential shape that departs from the conventional triangular circumference for bicycle saddles. The adjustable seating portions 604 a, 604 b are each roughly circular in nature and collectively would form an elliptical shape. Moreover, the adjustable seating portions 604 a, 604 b are relatively small, roughly corresponding to the size of the user's palm (or roughly 2 to 3 inches across (or 50.8 mm to 76.2 mm)), according to an embodiment of the invention.

The adjustable seating portions 604 a, 604 b are also shown in a top down view in FIG. 06 and may include a region (shown darkened) that corresponds to the user's ischial tuberosities. The padded adjustable seating portions 604 a, 604 b may include firmer sections (e.g. the darkened area would have a higher Shore Durometer measurement) underneath the rider's weight-bearing spot, according to an embodiment of the invention. Similarly, these regions on the adjustable seating portions 604 a, 604 b may also include padding and/or cushioning material, according an embodiment of the invention.

The bicycle saddle 606 may be configured in a manner consistent with the bicycle saddles shown in FIGS. 2-5, according to an embodiment of the invention. Accordingly, the saddle 606 includes two fixing rails 609 that attach to a bicycle stem 610 that itself attaches to the bicycle frame (not shown). The two fixing rails 609 attach to a foundation plate 612 that itself holds a threaded adjuster 608 placed inside a box section 607 on each side of the saddle 606. The threaded adjuster 608 allows for the two adjustable seating portions 604 a, 604 b of the bicycle saddle 606 to be brought either closer together or farther apart to match the width of the user's ischial tuberosities, according to an embodiment of the invention.

FIG. 07 illustrates an adjustable bicycle saddle 706 that aims to provide a proper distance between the user's ischial tuberosities and minimize the stress on the user's posterior area, according to an embodiment of the invention. The bicycle saddle 706 includes two adjustable seating portions 704 a, 704 b that may be spaced apart at an optimal distance between the user's ischial tuberosities, according to an embodiment of the invention. The adjustable seating portions 704 a, 704 b may comprise a roughly circular circumferential shape that differs from the conventional triangular circumference for bicycle saddles and aims to further reduce rider injuries. The adjustable seating portions 704 a, 704 b are each roughly circular in nature. Moreover, the adjustable seating portions 704 a, 704 b are relatively small, roughly corresponding to the size of the user's palm (or roughly 2 to 3 inches across (or 50.8 mm to 76.2 mm)), according to an embodiment of the invention.

The adjustable seating portions 704 a, 704 b are also shown in a top down view and may include a region (shown darkened) that corresponds to the user's ischial tuberosities. The adjustable seating portions 704 a, 704 b may include firmer sections (e.g. the darkened area) underneath the rider's weight-bearing spot, according to an embodiment of the invention. Similarly, these regions on the adjustable seating portions 704 a, 704 b may also include padding and/or cushioning material of various Shore Durometer measurements, according an embodiment of the invention.

The bicycle saddle 706 may be configured in a manner consistent with the bicycle saddles shown in FIGS. 2-6, according to an embodiment of the invention. Accordingly, the saddle 706 includes two fixing rails 709 that attach to a bicycle stem 710 that itself attaches to the bicycle frame (not shown). The two fixing rails 709 attach to a foundation plate 712 that itself holds a threaded adjuster 708 placed inside a box section similar to the box section 607 shown in FIG. 06. The threaded adjuster 708 allows for the two adjustable seating portions 704 a, 704 b of the bicycle saddle to be brought either closer together or farther apart, to match the width of the user's ischial tuberosities, according to an embodiment of the invention.

FIG. 08 illustrates a bicycle saddle 800 having a pair of rails 809 that allow the for forward/backward adjustment of the two adjustable seating portions of the bicycle saddle 800, according to an embodiment of the invention. FIG. 08 illustrates the two adjustable seating portions, such as the adjustable seating portions 704 a, 704 b shown in FIG. 07, as a combined ellipsis 810. Of course, to adjust saddle 800 to match the user's ischial tuberosities, the saddle 800 would need to comprise two separate adjustable seating portions (e.g., 704 a, 704 b) that covered each of the rail areas 809 to the edge of the worm 808, according to an embodiment of the invention. The saddle 800 has an overall elliptical circumference as opposed to the conventional triangular circumference in order to minimize rider injuries. Thus, the saddle 800 has been developed to hold a minimal surface area of the user's posterior, focused on the user's ischial tuberosities.

The bicycle saddle 800 includes a pair of base plates 812, and a slot in the base plates allows for sideways movement of each adjustable seating portion of the bicycle saddle 800, according to an embodiment of the invention. Similarly, another slot in the box section allows for forward/backward movement of a respective half of the bicycle saddle 800, according to an embodiment of the invention. The saddle 800 includes a worm 808, or a similar screw, that facilitates adjustments between the two adjustable seating portions of the saddle 800. Thus, by using these adjustment mechanisms, the bicycle saddle 800 may be configured to adjust to each rider's unique physiology as represented by the width of the user's ischial tuberosities.

FIG. 09 illustrates a bicycle saddle 900 having one adjuster 909 on each adjustable seating portion and three slots 906 on each adjustable seating portion to keep the seat elements in line, according to an embodiment of the invention. This particular embodiment has no requirement for the worm shown in FIG. 08. Of course, to adjust saddle 900 to match the user's ischial tuberosities, the saddle 900 would comprise two separate adjustable seating portions (e.g., the adjustable seating portions 1004 a, 1004 b shown in FIG. 10) that covered each of the rail areas 909 to the edge of the worm 908, according to an embodiment of the invention. The saddle 900 has an overall elliptical circumference as opposed to the conventional triangular circumference to minimize user injuries. Thus, the saddle 900 has been developed to hold a minimal surface area of the user's posterior, focused on the user's ischial tuberosities.

Each adjustable seating portion of the saddle 900 includes a rail 909, and each rail has three base plates 906. A first baseplate 906 a, close to the forward-facing area of the saddle 900 includes a slot that allows sideways movement, such that two adjustable seating portions of the saddle 0900 may be brought closer together. A second baseplate 906 b, close the back-facing area of the saddle 900 includes a slot in a box section that allows forward/backwards movement. A middle baseplate 906 c includes a wingnut 912 that may be used to secure the rail, according to an embodiment of the invention. With the rails allowing forward/backward adjustment, there is no need for the slots on the baseplate to do the same. Thus, the saddle 900 may be adjusted into a variety of configurations to best fit each given rider's unique physiology as expressed by the width of the user's ischial tuberosities.

FIG. 10 illustrates a saddle 1000 having two adjustable seating portions 1004 a, 1004 b, according to an embodiment of the invention. The adjustable seating portions 1004 a, 1004 b are compatible with the saddle designs shown in previous figures. In other words, the two adjustable seating portions 1004 a, 1004 b could be mounted on the supporting structures shown in FIG. 06-09.

The adjustable seating portions 1004 a, 1004 b have been formed to accommodate the shape of the rider's physiology. Thus, a front region 1002 on each half 1004 a, 1004 b facilitates the placement of the rider's upper thigh. The saddle 1000 aims to allow the user to sit on the bicycle at an appropriate weight bearing location with the ischial tuberosities bearing up the weight of the rider's upper body with only minimal portions of the rest of the user's body even touching the saddle 1000.

FIG. 11 illustrates a saddle 1100 that combines elements of the saddle 900 shown in FIG. 09 with the saddle 1000 shown in FIG. 10, according to an embodiment of the invention. Thus, the saddle 1100 includes two rails 1109 that control the two adjustable seating portions of the saddle 1100. A slot in the baseplate on the saddle 1100 allows the baseplate to move sideways, allowing the two adjustable seating portions of the saddle 1100 to move closer or farther apart. The saddle 1100 includes a slot in a box section to accommodate forward/backwards movement. With the rails allowing forward/backward adjustment, there is no need for slots on the baseplate to do the same thing, according to an embodiment of the invention.

FIG. 12 illustrates a saddle 1200 having two adjustable seating portions 1210 a, 1210 b. Each adjustable seating portion of the saddle 1200 includes at least one groove 1209 to act as a gutter when the saddle 1200 is wet to allow water to run off rather than pool on the saddle 1200. The pooling of water on the saddle 1200 is possibly more significant than conventional bicycle saddles because the seat of the saddle 1200 is concave rather than convex like the conventional bicycle seat, according to an embodiment of the invention. The concave saddle 1200 will be employed to assist the rider in maintaining a proper and comfortable position while riding. The gutter grooves 1209 should be placed away from the main pressure points for the saddle 1200 (marked here as circles 1206) to avoid creating a “friction” point that could cause the rider discomfort or injury. The pressure points 1206 should also represent the points corresponding to the user's ischial tuberosities, assuming that the saddle 1200 has been properly fitted.

FIG. 13 illustrates a front right-side perspective view of a saddle 1300 having two adjustable seating portions 1310 a, 1310 b, according to an embodiment of the invention. The two adjustable seating portions 1310 a, 1310 b are connected via a joining piece 1302. The two adjustable seating portions 1310 a, 1310 b are held by clamps 1304 a, 1304 b. The joining piece 1302 is shown as a cylinder but could have other shapes, such as a rectangular prism, so long as it was capable of supporting the two adjustable seating portions 1310 a, 1310 b and holding them in a proper position with respect to the user's ischial tuberosities.

The front region 1308 (shown as a shaded portion) of each adjustable seating portion 1310 a, 1310 b is lower than a rear region 1309 (shown as a shaded) of each adjustable seating portion 1310 a, 1310 b, according to an embodiment of the invention. The rear region 1309 is also somewhat concave while front region 1308 is also somewhat downward slopping. The overall shape of the front region 1308 and the back portion 1309 of each adjustable seating portion 1310 a, 1310 b helps the rider's posterior stay properly supported on the rider's ischial tuberosities, according to an embodiment of the invention. The adjustable seating portion 1310 a is shaped so as to settle the rider's ischial tuberosity into a region 1307 located at a proximal center of the adjustable seating portion 1310 a. The region 1307 may receive extra padding or include a material of a higher Shore Durometer reading than the much of the rest of the adjustable seating portion 1310 a, according to an embodiment of the invention. The adjustable seating portion 1310 b has not been marked with the shadings shown for the adjustable seating portion 1310 a but would be so similarly shaped and have similar regions, although accounting for the differences in left/right symmetry of the human body, according to an embodiment of the invention.

Each adjustable seating portion 1310 a, 1310 b could have a range of different proportions. However, experimentation has shown that the adjustable seating portions 1310 a, 1310 b may be fairly small, roughly the size of an average human palm (roughly 2-6 inches or 5.08 cm to 15.24 cm) from side to side with roughly a 4-36 square inch (25.81 cm² to 232.26 cm²) surface area, according to various embodiments of the invention. However, for many years, the trend in racing saddles has been to reduce their size significantly. Consequently, a 2-3-inch (5.08 cm to 7.62 cm) diameter for the adjustable seating portions 1310 a, 1310 b is more likely with a surface area from 4-9 square inches (25.81 cm² to 58.1 cm²). FIG. 13 illustrates the physical structure for the saddle 1300 and does not include the softer covering elements that could be added to the saddle 1300 in some embodiments.

As shown in FIG. 13, an open space (marked A) divides the two adjustable seating portions 1310 a, 1310 b with the intention to provide enhanced comfort and safety for the user and intended to solve some of the health and safety problems previously mentioned. Commercial embodiments of the invention may include adjustable seating portions 1310 a, 1310 b of differing sizes. A user should select a seating size whose combined distances from seat center to seat edge are less than the user's ischial tuberosity width, e.g., a user with an ischial tuberosity width of 14 cm could choose seats having an overall width of 7.62 cm (the distance from each seat's center to seat edge is 3.81 cm, leaving a separation between the two seats of 6.38 cm (14 cm−(3.82 cm×2)=6.38 cm).

The bars 1305 may be inserted into a clamp held on the bicycle frame (not shown). Such an arrangement allows the seat 1300 to be removed. Thus, for example, two different riders with differing ischial tuberosities could easily share the same bicycle. Of course, there are other means for attaching the seat 1300 to the bicycle frame, such as a post on the joining piece 1302 that attaches (or clamps) to the bicycle frame.

FIG. 14 illustrates a rear right-side perspective view of a saddle 1400 having two adjustable seating portions 1410 a, 1410 b, according to an embodiment of the invention. The two adjustable seating portions 1410 a, 1410 b are connected via a joining piece 1402. The two adjustable seating portions 1410 a, 1410 b are held by clamps 1404 a, 1404 b that are fastened by wheels 1406 a, 1406 b. The clamps 1404 a, 1404 b are attached to a respective adjustable seating portion 1410 a, 1410 b.

In use, the adjustable seating portions 1410 a, 1410 b may slide down the joining piece 1402 away from each other (or even towards each other) until the distance between the load bearing sections (the region 1307 shown in FIG. 13) of the adjustable seating portions 1410 a, 1410 b matches the distance between the user's ischial tuberosities. Once this distance has been matched, then the wheels 1406 a, 1406 b may be clamped into place to fasten the adjustable seating portions 1410 a, 1410 b in place to the joining piece 1402, according to an embodiment of the invention.

The joining piece 1402 is shown as a cylinder but may have other shapes, such as a rectangular prism, so long as it is capable of supporting the two adjustable seating portions 1410 a, 1410 b and so long as the joining piece 1402 could accommodate fastening devices such as the clamps 1404 a, 1404 b.

The front region 1408 of each adjustable seating portion 1410 a, 1410 b is lower than a rear region 1409 of each adjustable seating portion 1410 a, 1410 b, according to an embodiment of the invention. The perimeters of the regions 1408, 1409 have similar shapes to the regions 1308, 1309 shown in FIG. 13 but have not been shaded here to avoid obscuring other features. The rear region 1409 is also somewhat concave while front region 1408 is also somewhat downward slopping. The overall shape of the front region 1408 and the back portion 1409 of each adjustable seating portion 1410 a, 1410 b helps the rider's posterior stay properly supported on the rider's ischial tuberosities, according to an embodiment of the invention. The adjustable seating portions 1410 a, 1410 b are shaped so as to settle the rider's ischial tuberosity into a matching region (e.g., the region 1307 shown in FIG. 13) that resides in roughly the center of each adjustable seating portion 1410 a, 1410 b.

The saddle 1400 includes a Y-shaped thigh support post 1412 that removably attaches to the joining piece 1402. The removable Y-shaped thigh support post 1412 may serve several functions for some riders. First, some riders may feel so accustomed to conventional bicycle saddles that they feel a need for the conventional triangular saddle shape or some approximation of it. For these riders, the removable Y-shaped thigh support post 1412 may offer them the security of a conventional saddle seat. Second, some riders may feel the need for thigh support during particularly tight turns and other maneuvers. These riders may lean a portion of their thigh on the removable Y-shaped thigh support post 1412 during a turn. Other riders may not find a need for the removable Y-shaped thigh support post 1412 and simply remove it from the saddle 1400 or never install it. One arm of the removable Y-shaped thigh support post 1412 attaches to the joining piece 1402 underneath the first adjustable seating portion 1410 a, and another arm of the removable Y-shaped thigh post 1412 attaches to the joining piece 1402 underneath the second adjustable seating portion 1410 b. The stem portion of the removable Y-shaped thigh support post 1412 could be any length, such as the length of the average human thigh, and a length from 6 to 18 inches (15.24 cm to 45.72 cm) would seem appropriate for most riders, according to an embodiment of the invention.

Each adjustable seating portion 1410 a, 1410 b could have a range of different proportions. However, experimentation has shown that the adjustable seating portions 1410 a, 1410 b may be fairly small, roughly the size of an average human palm or roughly 2-6 inches (or 5.08 cm to 15.24 cm) from side to side with roughly a 4-36 square inch (25.81 cm² to 232.26 cm²) surface area, according to various embodiments of the invention. However, for many years, the trend in racing saddles has been to reduce their size significantly. Consequently, a 2-3-inch (5.08 cm to 7.62 cm) diameter for the adjustable seating portions 1410 a, 1410 b is more likely with a surface area from 4-9 square inches (25.81 cm² to 58.1 cm²). FIG. 14 illustrates the physical structure for the saddle 1400 and does not include the softer covering elements that could be added to the saddle 1400 in some embodiments.

As shown in FIG. 14, an open space (similar to the distance marked “A” in FIG. 13) divides the two adjustable seating portions 1410 a, 1410 b with the intention to provide enhanced safety for the user and intended to solve some of the health and safety problems previously mentioned. Commercial embodiments of the invention may include adjustable seating portions 1410 a, 1410 b of differing sizes. A user should select a seating size whose combined distances from seat center to seat edge are less than the user's ischial tuberosity width, e.g., a user with an ischial tuberosity width of 14 cm could choose seats having an overall width of 7.62 cm (the distance from each seat's center to seat edge is 3.81 cm, leaving a separation between the two seats of 6.38 cm (14 cm−(3.82 cm×2)=6.38 cm).

The bars 1405 may be inserted into a clamp held on the bicycle frame (not shown). Such an arrangement allows the seat 1400 to be removed. Thus, for example, two different riders with differing ischial tuberosities could easily share the same bicycle. Of course, there are other means for attaching the seat 1400 to the bicycle frame, such as a post on the joining piece 1402 that attaches (or clamps) to the bicycle frame.

FIG. 15 illustrates a front plan view of a saddle 1500 having two adjustable seating portions 1510 a, 1510 b, according to an embodiment of the invention. The two adjustable seating portions 1510 a, 1510 b are connected via a joining piece 1502. The two adjustable seating portions 1510 a, 1510 b are held by clamps 1504 a, 1504 b that are fastened by wheels 1506 a, 1506 b. The clamps 1504 a, 1504 b are attached to a respective adjustable seating portion 1510 a, 1510 b.

In use, the adjustable seating portions 1510 a, 1510 b may slide down the joining piece 1502 away from each other (or even towards each other) until the distance between the load bearing sections (equivalent to the region 1307 shown in FIG. 13) of the adjustable seating portions 1510 a, 1510 b matches the distance between the user's ischial tuberosities. Once this distance has been matched, then the wheels 1506 a, 1506 b may be clamped into place to fasten the adjustable seating portions 1510 a, 1510 b in place to the joining piece 1502, according to an embodiment of the invention.

The joining piece 1502 is shown as a cylinder but may have other shapes, such as a rectangular prism, so long as it is capable of supporting the two adjustable seating portions 1510 a, 1510 b and so long as the joining piece 1502 could accommodate fastening devices such as the clamps 1504 a, 1504 b.

The front region 1508 of each adjustable seating portion 1510 a, 1510 b is lower than a rear region 1509 of each adjustable seating portion 1510 a, 1510 b, according to an embodiment of the invention. The perimeters of the regions 1508, 1509 have similar shapes to the regions 1308, 1309 shown in FIG. 13 but have not been shaded here to avoid obscuring other features. The rear region 1509 is also somewhat concave while front region 1508 is also somewhat downward slopping. The overall shape of the front region 1508 and the back portion 1509 of each adjustable seating portion 1510 a, 1510 b helps the rider's posterior stay properly supported on the rider's ischial tuberosities, according to an embodiment of the invention.

FIG. 16 illustrates a rear plan view of a saddle 1600 having two adjustable seating portions 1610 a, 1610 b, according to an embodiment of the invention. The two adjustable seating portions 1610 a, 1610 b are connected via a joining piece 1602. The two adjustable seating portions 1610 a, 1610 b are held by clamps 1604 a, 1604 b that are fastened by wheels 1606 a, 1606 b. The clamps 1604 a, 1604 b are attached to a respective adjustable seating portion 1610 a, 1610 b.

In use, the adjustable seating portions 1610 a, 1610 b may slide down the joining piece 1602 away from each other (or even towards each other) until the distance between the load bearing sections (e.g., corresponding to the region 1307 shown in FIG. 13) of the adjustable seating portions 1610 a, 1610 b matches the distance between the user's ischial tuberosities. Once this distance has been matched, then the wheels 1606 a, 1606 b may be clamped into place to fasten the adjustable seating portions 1610 a, 1610 b in place to the joining piece 1602, according to an embodiment of the invention.

The joining piece 1602 is shown as a cylinder but may have other shapes, such as a rectangular prism, so long as it was capable of supporting the two adjustable seating portions 1610 a, 1610 b and so long as the joining piece 1602 could accommodate fastening devices such as the clamps 1604 a, 1604 b. The clamps 1604 a, 1604 b may include internal rockers 1613 s that are respectively mounted to spring 1611 s, according to an embodiment of the invention. The rocker 1613 and spring 1611 allow each adjustable seating portion 1610 a, 1610 b to flex by some amount (e.g., from 0 to 30 degrees) both inward and outward. The springs 1611 may have various spring constants from loose to stiff. The springs 1611 and rockers 1613 are shown here in a cutaway but could be mounted in a variety of different ways. For example, the springs 1611 and rockers 1613 could be mounted directly on the adjustable seating portions 1610 a, 1610 b, according to an alternative embodiment of the invention.

The front region 1608 of each adjustable seating portion 1610 a, 1610 b is lower than a rear region 1609 of each adjustable seating portion 1610 a, 1610 b, according to an embodiment of the invention. The perimeters of the regions 1608, 1609 have similar shapes to the regions 1308, 1309 shown in FIG. 13 but have not been shaded here to avoid obscuring other features. The rear region 1609 is also somewhat concave while front region 1608 is also somewhat downward slopping. The overall shape of the front region 1608 and the back portion 1609 of each adjustable seating portion 1610 a, 1610 b helps the rider's posterior stay properly supported on the rider's ischial tuberosities, according to an embodiment of the invention.

FIG. 17 illustrates a right-side view of a saddle 1700 showing an adjustable seating portion 1710 a, according to an embodiment of the invention. The adjustable seating portion 1710 a would be accompanied on the saddle 1700 by another adjustable seating portion, such as the adjustable seating portion 1610 b shown in FIG. 16. The adjustable seating portion 1710 a is connected via a joining piece 1702 to the other adjustable seating portion. The adjustable seating portion 1710 a is held by a clamp 1704 a that is fastened by a wheel 1706 a to the joining piece 1702. The clamp 1704 a is attached to the adjustable seating portion 1710 a.

In use, the adjustable seating portion 1710 a may slide down the joining piece 1702 away from the other adjustable seating portion (or even towards the other adjustable seating portion) until the distance between the load bearing sections (corresponding to the region 1307 shown in FIG. 13) of the adjustable seating portions matches the distance between the user's ischial tuberosities. Once this distance has been matched, then the wheel 1706 a may be clamped into place to fasten the adjustable seating portion 1710 a in place around the joining piece 1702, according to an embodiment of the invention.

The joining piece 1702 is shown as a cylinder but may have other shapes, such as a rectangular prism, so long as it was capable of supporting the two adjustable seating portions, and so long as the joining piece 1702 could accommodate fastening devices such as the clamp 1704 a.

The front region 1708 of the adjustable seating portion 1710 a is lower than a rear region 1709 of the adjustable seating portion 1710 a, according to an embodiment of the invention. The perimeters of the regions 1708, 1709 have similar shapes to the regions 1308, 1309 shown in FIG. 13 but have not been shaded here to avoid obscuring other features. The rear region 1709 is also somewhat concave while front region 1708 is also somewhat downward slopping. The overall shape of the front region 1708 and the back portion 1709 of the adjustable seating portion 1710 a helps the rider's posterior stay properly supported on the rider's ischial tuberosities, according to an embodiment of the invention.

FIG. 18 illustrates a left-side view of a saddle 1800 showing an adjustable seating portion 1810 b, according to an embodiment of the invention. The adjustable seating portion 1810 b would be accompanied on the saddle 1800 by another adjustable seating portion, such as the adjustable seating portion 1610 a shown in FIG. 16. The adjustable seating portion 1810 b is connected via a joining piece 1802 to the other adjustable seating portion. The adjustable seating portion 1810 b is held by a clamp 1804 a that is fastened by a wheel 1806 b to the joining piece 1802. The clamp 1804 b is attached to the adjustable seating portion 1810 b.

In use, the adjustable seating portion 1810 b may slide down the joining piece 1802 away from the other adjustable seating portion (or even towards the other adjustable seating portion) until the distance between the load bearing sections (e.g., the region 1307 in FIG. 13) of the adjustable seating portions matches the distance between the user's ischial tuberosities. Once this distance has been matched, then the wheel 1806 b may be clamped into place to fasten the adjustable seating portion 1810 b in place around the joining piece 1802, according to an embodiment of the invention.

The joining piece 1802 is shown as a cylinder but may have other shapes, such as a rectangular prism, so long as it is capable of supporting the two adjustable seating portions, and so long as the joining piece 1802 could accommodate fastening devices such as the clamp 1804 b.

The front region 1808 of the adjustable seating portion 1810 b is lower than a rear region 1809 of the adjustable seating portion 1810 b, according to an embodiment of the invention. The perimeters of the regions 1808, 1809 have similar shapes to the regions 1308, 1309 shown in FIG. 13 but have not been shaded here to avoid obscuring other features. The rear region 1809 is also somewhat concave while front region 1408 is also somewhat downward slopping. The overall shape of the front region 1808 and the back portion 1809 of the adjustable seating portion 1810 b helps the rider's posterior stay properly supported on the rider's ischial tuberosities, according to an embodiment of the invention. The adjustable seating portion 1410 b is shaped so as to settle the rider's ischial tuberosity into a matching region (e.g., the region 1307 shown in FIG. 13) that resides in roughly the center of the adjustable seating portion 1810 b.

The adjustable seating portion 1810 b could have a range of different proportions. However, experimentation has shown that the adjustable seating portion 1810 b may be fairly small, roughly the size of an average human palm or roughly 2-6 inches (or 5.08 cm to 15.24 cm) from side to side with roughly a 4-36 square inch (25.81 cm² to 232.26 cm²) surface area, according to various embodiments of the invention. However, for many years, the trend in racing saddles has been to reduce their size significantly. Consequently, a 2-3-inch (5.08 cm to 7.62 cm) diameter for the adjustable seating portions 1810 a, 1810 b is more likely with a surface area from 4-9 square inches (25.81 cm² to 58.1 cm²). FIG. 18 illustrates the physical structure for the saddle 1800 and does not include the softer covering elements that could be added to the saddle 1800 in some embodiments.

The bar 1805 may be inserted into a clamp held on the bicycle frame (not shown). Such an arrangement allows the seat 1800 to be removed. Thus, for example, two different riders with differing ischial tuberosities could easily share the same bicycle. Of course, there are other means for attaching the seat 1800 to the bicycle frame, such as a post on the joining piece 1802 that attaches (or clamps) to the bicycle frame.

FIG. 19 illustrates a top plan view of a saddle 1900 having two adjustable seating portions 1910 a, 1910 b, according to an embodiment of the invention. The two adjustable seating portions 1910 a, 1910 b are connected via a joining piece 1902. The two adjustable seating portions 1910 a, 1910 b are held by clamps (e.g., clamps 1604 a, 1604 b that are fastened by wheels 1606 a, 1606 b shown in FIG. 16).

In use, the adjustable seating portions 1910 a, 1910 b may slide down the joining piece 1902 away from each other (or even towards each other) until the distance between the load bearing sections (corresponding to the region 1307 shown in FIG. 13) of the adjustable seating portions 1910 a, 1910 b matches the distance between the user's ischial tuberosities. Once this distance has been matched, then the wheels (e.g., the wheels 1606 a, 1606 b shown in FIG. 16) may be clamped into place to fasten the adjustable seating portions 1910 a, 1910 b in place around the joining piece 1902, according to an embodiment of the invention.

The joining piece 1902 may have a variety of shapes, such as a cylinder or rectangular prism, so long as it was capable of supporting the two adjustable seating portions 1910 a, 1910 b and so long as the joining piece 1902 could accommodate fastening devices such as clamps.

The front region 1908 of each adjustable seating portion 1910 a, 1910 b is lower than a rear region 1909 of each adjustable seating portion 1910 a, 1910 b, according to an embodiment of the invention. The perimeters of the regions 1908, 1909 have similar shapes to the regions 1308, 1309 shown in FIG. 13 but have not been shaded here to avoid obscuring other features. The rear region 1909 is also somewhat concave while front region 1908 is also somewhat downward slopping. The overall shape of the front region 1908 and the back portion 1909 of each adjustable seating portion 1910 a, 1910 b helps the rider's posterior stay properly supported on the rider's ischial tuberosities, according to an embodiment of the invention. The adjustable seating portions 1910 a, 1910 b are shaped so as to settle the rider's ischial tuberosity into a matching region (e.g., the region 1307 shown in FIG. 13) that resides in roughly the center of each adjustable seating portion 1910 a, 1910 b.

Each adjustable seating portion 1910 a, 1910 b could have a range of different proportions. However, experimentation has shown that the adjustable seating portions 1910 a, 1910 b may be fairly small, roughly the size of an average human palm or roughly 2-6 inches (or 5.08 cm to 15.24 cm) from side to side with roughly a 4-36 square inch (25.81 cm² to 232.26 cm²) surface area, according to various embodiments of the invention. However, for many years, the trend in racing saddles has been to reduce their size significantly. Consequently, a 2-3-inch (5.08 cm to 7.62 cm) diameter for the adjustable seating portions 1910 a, 1910 b is more likely with a surface area from 4-9 square inches (25.81 cm² to 58.1 cm²). FIG. 19 illustrates the physical structure for the saddle 1900 and does not include the softer covering elements that could be added to the saddle 1900 in some embodiments.

As shown in FIG. 19, an open space (similar to the open space marked “A” in FIG. 13) divides the two adjustable seating portions 1910 a, 1910 b with the intention to provide enhanced safety for the user and intended to solve some of the health and safety problems previously mentioned. Commercial embodiments of the invention may include adjustable seating portions 1910 a, 1910 b of differing sizes. A user should select a seating size whose combined distances from seat center to seat edge are less than the user's ischial tuberosity width, e.g., a user with an ischial tuberosity width of 14 cm could choose seats having an overall width of 7.62 cm (the distance from each seat's center to seat edge is 3.81 cm, leaving a separation between the two seats of 6.38 cm (14 cm−(3.82 cm×2)=6.38 cm).

The bars 1905 may be inserted into a clamp held on the bicycle frame (not shown). Such an arrangement allows the seat 1900 to be removed. Thus, for example, two different riders with differing ischial tuberosities could easily share the same bicycle. Of course, there are other means for attaching the seat 1900 to the bicycle frame, such as a post on the joining piece 1902 that attaches (or clamps) to the bicycle frame.

FIG. 20 illustrates an exploded view of a saddle 2000 having two adjustable seating portions 2010 a, 2010 b, according to an embodiment of the invention. The two adjustable seating portions 2010 a, 2010 b are connected via a joining piece 2002. The two adjustable seating portions 2010 a, 2010 b are held by clamps 2004 a, 2004 b that are fastened by wheels 2006 a, 2006 b. The clamps 2004 a, 2004 b are attached to a respective adjustable seating portion 2010 a, 2010 b.

In use, the adjustable seating portions 2010 a, 2010 b may slide down the joining piece 2002 away from each other (or even towards each other) until the distance between the load bearing sections (e.g., corresponding to the region 1307 shown in FIG. 13) of the adjustable seating portions 2010 a, 2010 b matches the distance between the user's ischial tuberosities. Once this distance has been matched, then the wheels 2006 a, 2006 b may be clamped into place to fasten the adjustable seating portions 2010 a, 2010 b in place around the joining piece 2002, according to an embodiment of the invention.

The joining piece 2002 is shown as a cylinder but may have other shapes, such as a rectangular prism, so long as it is capable of supporting the two adjustable seating portions 2010 a, 2010 b and so long as the joining piece 2002 could accommodate fastening devices such as the clamps 2004 a, 2004 b.

The joining piece 2002 may include a series of markings 2014 that aid in the adjustment of the adjustable seating portion 2010 a and the adjustable seating portion 2010 b to match the width of the user's ischial tuberosities. The markings 2014 could comprise one or more relevant measuring units, such as inches or millimeters, or could even comprise unique units that were relative and/or non-standard. In any event the markings 2014 should be regularly spaced across the joining piece 2002 to simplify adjustment, according to an embodiment of the invention. The clamps 2004 a, 2004 b could include an open viewing portion so that the user could align the adjustable seating portions 2010 a, 2010 b with the markings 2014. Alternatively, the user could use the front edge of clamps 2004 a, 2004 b as a marking position. This approach should work well if the user also knows the distance between the front edge of the clamp and the precise location on each adjustable seating portion 2010 a, 2010 b that is intended to match the user's ischial tuberosities, according to an embodiment of the invention.

The front region 2008 of each adjustable seating portion 2010 a, 2010 b is lower than a rear region 2009 of each adjustable seating portion 2010 a, 2010 b, according to an embodiment of the invention. The perimeters of the regions 2008, 2009 have similar shapes to the regions 1308, 1309 shown in FIG. 13 but have not been shaded here to avoid obscuring other features. The rear region 2009 is also somewhat concave while front region 2008 is also somewhat downward slopping. The overall shape of the front region 2008 and the back portion 2009 of each adjustable seating portion 2010 a, 2010 b helps the rider's posterior stay properly supported on the rider's ischial tuberosities, according to an embodiment of the invention. The adjustable seating portions 2010 a, 2010 b are shaped so as to settle the rider's ischial tuberosity into a matching region (e.g., the region 1307 shown in FIG. 13) that resides in roughly the center of each adjustable seating portion 2010 a, 2010 b.

Each adjustable seating portion 2010 a, 2010 b could have a range of different proportions. However, experimentation has shown that the adjustable seating portions 2010 a, 2010 b may be fairly small, roughly the size of an average human palm or roughly 2-6 inches (or 5.08 cm to 15.24 cm) from side to side with roughly a 4-36 square inch (25.81 cm² to 232.26 cm²) surface area, according to various embodiments of the invention. However, for many years, the trend in racing saddles has been to reduce their size significantly. Consequently, a 2-3-inch (5.08 cm to 7.62 cm) diameter for the adjustable seating portions 2010 a, 2010 b is more likely with a surface area from 4-9 square inches (5.81 cm² to 58.1 cm²). FIG. 20 illustrates the physical structure for the saddle 2000 and does not include the softer covering elements that could be added to the saddle 2000 in some embodiments.

Once assembled, an open space (similar to the area marked “A” in FIG. 13) divides the two adjustable seating portions 2010 a, 2010 b with the intention to provide enhanced safety for the user and intended to solve some of the health and safety problems previously mentioned. Commercial embodiments of the invention may include adjustable seating portions 2010 a, 2010 b of differing sizes. A user should select a seating size whose combined distances from seat center to seat edge are less than the user's ischial tuberosity width, e.g., a user with an ischial tuberosity width of 14 cm could choose seats having an overall width of 7.62 cm (the distance from each seat's center to seat edge is 3.81 cm, leaving a separation between the two seats of 6.38 cm (14 cm−(3.82 cm×2)=6.38 cm).

The bars 2005 may be inserted into a clamp held on the bicycle frame (not shown). Such an arrangement allows the seat 2000 to be removed. Thus, for example, two different riders with differing ischial tuberosities could easily share the same bicycle. Of course, there are other means for attaching the seat 2000 to the bicycle frame, such as a post on the joining piece 2002 that attaches (or clamps) to the bicycle frame.

Some embodiments of the invention may further comprise gel or a gel-covered structure to spread pressure from the user's weight and avoid damage to the user's spine. The gel could comprise various hardness measurements on an appropriate Shore Durometer scale, e.g., 15-30 on the Shore 00 scale.
